There appear to be at least three chief branches of the house, on Old Wyk, Great Wyk, and Orkmont (III: 941. IV: 258)

The Goodbrothers of Great Wyk have a black-and-gold warhorn on red as their symbol (IV: 18)

There are several branches of the Goodbrothers throughout Great Wyk. Among them are those who hold the towers of Downdelving, Crow Spike Keep, and Corpse Lake (IV: 26)
